On Electric Bike Project # 1, Bionx PL350. I garbage picked a bike with larger front gears, 30T, 40T, and 50T. Installed bigger crankset on electric bike. Leave on largest 50T front gear and 16T rear gear and all is good. Never shift gears.
Now I am building Electric Bike Project # 2. Can not find a garbage bike with large front chainring. Look at new ones. Prices are almost the same as a Kmart bike.
As of now, large chainring is 4 bolt, 104 BCD. Crank is 170mm. Bottom Bracket is FSA MEGA EXO. Could change the whole crankset and bottom bracket if necessary?
Is there any online used bike part sellers? Think steel chainrings are better then aluminum? Stronger. For junk yard car parts go to car-part.com Search auto junk yards all over the country. Give me a used frame with a large steel chainrings and aluminum cranks for $50 or so and I will be happy.
BCD = Bolt Center Distance
T = Tooth
